Read-only state
With Redux, it is not possible to modify the application state directly. It is only possible to change the state by dispatching actions. This principle makes state changes predictable: if no action happened, the application state will not change. Furthermore, actions are processed one at a time, so we do not have to deal with race conditions. Finally, actions are plain JavaScript objects, which makes them easy to serialize, log, store, or replay. As a result, debugging and testing a Redux application becomes very easy to do.
